asp.net static method pop up dialog box implementation ideas

Still don't say nonsense, go straight to code. For beginners... It's basically a little window that pops up JavaScript, which is basically a defined DIV

 
　　 /// <summary> 
///  The pop-up JavaScript A small window , It's actually defined 1 a DIV 
/// </summary> 
/// <param name="js"> Window information </param> 
public static void Alert(string message) 
{ 
message = "<div style='border:darkturquoise 1px solid; width:200px;color: blue; font-style: normal; font-family:  Regular script _GB2312;height:auto; background-color: #f4f8ff;padding:15px 0px; text-align:center; font-size: 23px;left: 360px; position: absolute; top: 200px;'>" + message + "</div>"; 
HttpContext.Current.Response.Write(message); 
}
